Answer:
23.41cm
Step-by-step explanation:
Using Pythagoras theorem
a²+b² = c²
Where a and b are sides of the triangle and c is the Hypotenuse.
If we substitute the values
B= 8 cm
A= 22 cm
22²+8² = c²
484 + 64= c²
√548 = c
C= 23.41
Hence, length AB is 23.41cm

Step-by-step explanation:
Answer:
The value is
Step-by-step explanation:
From the question we are told that
The null hypothesis is 
The level of significance is 
From the z table the critical value of
considering the two tails of the normal curve( This is because this a two tailed test ) is

Hence the critical value is
For the top angles you would solve them by setting them equal to each other, so you would do 3x+5=17x-70. You can then add 70 to both sides, getting 3x+75=17x. You can then subtract 3x from both sides, getting 75=14x. You then divide both sides, getting 5 5/14 or around 5.36 as x. You can then add plug that into 3x+5, getting around 21.07. You can then make the equation R=180-21.07. You'd get 158.93.
A) set them equal to 180° so it should be 180=5x+10 and x=34 plug it in and VRX=56° and WRV=124°
